- A Ashow a frame for supporting the work ing parts of my improved printing-press.

B is a platen hung upon the shaft Oat an --angle from a horizontal or fr bn a vertical positio'n,which platen Brests iipon the sleeve or collar, D, through which sleeve or collar 1) runs the mainshaft E. This shaft Ehasupon one side the large cog-wheel G, gearing into the pinion gH, upon the" fly-wheel shaft I, wh1le,' upon thejoppositeside-of the shaft F: 18 the blank-crank J, having out upon its inner side a earn ofthe requiredshape, which cam,through the arm L and its roller Z, serves'to operate the trip M, as hereinafter shown. The cogw'heel G has out upon its inner side the cam N, which cam N, through'thc arm 0 and its roller '0, .operatesgthe nipper'arrnsfl? P; ,The cog-wheel G-and blank-crank J: form cranks, gto which one end of the connecting-rods Q Q I are attached, their opposite ends being attached to the shaft R, passing through the" back'of the bedB, and upon which shaft R are the roller-arms 3.

P P are nipper-arms on either side ofthe frame AIA, for supporting and carrying the sheet-taking nippers T and T, which nipperarms PP, are hung upon the rod. U, and are rocked to and from the stationary feed-table V, through the {arm 0 and its roller 0, playing in the cam Nin the cog-wheelG. These nipper-arms l? P also support and carry the rod W, orits equivalent, attached to the nipper-arms P l? attheir forward ends, and under the nippers T and T.

T and T show the sheet-tabling nippers, the

upper nippers being designated by T and the lo'wer'ones by T. Both thenpper.j(T)'andthe under (T) nippers are {hinged or swiveled upon the shaft X. This shaft- X is held in the journal-boxes Y, one at either forward end of the nipper-arms 1. P, in which journal-boxes Y it (the shaft X) freely plays when the nipdow'gn to the rodW or'its equivalent, and holds ,ingt'them-there.

' b shows a short eccentric-shaft held in the journal-box c, firmly attached'upon the shaft X. This short eccentric-shaft b is provided at one end with the eccentric d, and at its other end is attached the crank-arm e,with its roller f. This eccentric d plays freely between the nippers T T, properly fitted for-such purpose. This crank-arm e, with its roller f, is operated by the trip M, as hereinafter shown, and aids in opening and closing the nippers T T. At the opposite end of the shaft X is attached the crank-arm g, with its roller h,

which crank-arm g, through its roller h, impinges upon the stationary slotted earn a and aids in opening and closing the nippers T T.

emsso of which is attached to the rod W, or its equiv:

one end of this roller K, one end of which and its other end to the platen B5 This coi'd paper tymp'an-sheet J" upon the roller K and give theproper tension and smoothness to the paper tyinpan-sheet J necessary for the receiving, carrying,"priuti'ng mrd delivering of ,thesheet. v i} I V shows a stationary feed-table, upon which estationary feed-table V the sheet tojbe printed is placed, in order that it (the sheet) may be taken therefrom by the nippersT andT. This feed-table Vis projected over and beyond the face-line of the platen B, for the purpose of allowing and insuring the passage of the printed the shield or guide m, in order that it may be properly deposited upon the pile-table V" be-- teeth the sheet catches or holdersk k. ,This stationary feed-table V has attached to it the supports a, for supporting the rod '1 by which rody the gages z are held. These gages z are bent or curved upward from heir ends,against which the sheet is laid, upward to the rod 3 upon which they are held, their curve at its commencement running nearly parallel with the feed-table V and gradually risingt'roi the feed-table Vuntil the gages z are in line with the object of these gages a being to straighten the edge of the sheet to be taken by the nippers T and T, should there be any upward curl of the edge of the sheet, (as is frequently the case,') and thus presentthe sheet properly and surely to the nippers T and T. This rod g may be slotted,and the gagesz held to the same by bolts and nuts, thus rendering the gagesz' adjustable. Upon one side of this stationary feed-table V are placed the vibrating upright a and cam-shaped piece I), operated by the pin 0" upon the trip M, for the purpose of raising the gages z and allowing table V by the nippers T and T.

' YPhesleeve or collar D, through which the main -shaftEruns,and upon and against which the platen B rests, has an arc of its circle cut lar D and bringing the plane portion of the same directly behind the plate B,the platen B the type or form) to prevent an impression being given by the type upon the sheet held upon the platen B.

J shows it tympan-sheet of paper, (intendalent,directly under the nippers T T ,while the' other or opposite end is attached to the roller. Kflwhich roller Kzis fastened to the platen Br, An elastic cord or spring, 10, is wound around cord or spring to is fastened to the roller K" or spring 11; serves to wind up or roll up the sheet under the table V and its reception by' the rod y, upon which rod y they are held,u

thc'sheet to be taken from the stationary feedaway, so that upon turning the sleeve or colmay v-ibrateback and be removed a sufficient distance-from the bed 13 (in which is placed C shows a handle attached firmly to the 7 der the stationary feed-table V, and properly v inclined for the reception of the printed sheets.

- This pile-table V is provided with the slidholders of the, sheets after they are printed. 3 These catches kin are pivoted loosely to the sliding ledge j, so that they may freely turn and rise upward from the pile-table V to allow the sheet to pass under them and be held in place by the weight of the catches in k.

These catches k kare In'ade si n'rpl y of wire or any suitable lightimateriahstraightfrom their point of attachment tothesliding ledge j and .gentlycurved upward, forward, or from the adjustable ledge j. When these catches k it rest upon the pile-table V, they stand at a slightangle from the perpendicular, in order that may rise sidewise as the printed sheets they are piled beneath'them. i i

m shows the shield or guide ,attachedto the stationary feed-table V on its under side, and properly curved to guide the sheets in their ransitlfron the rollingtympan'to the piletable V. Y

B is a vibrating bed, in which the typeor form is 'placed,which vibrating bed B is hung upon the shaft 0, upon which shaft G is also hung the platen B. j For thepurpose of giving more precision and truth to the impression, the platen B and bed B are hung upon the same shaft, G, as all lateral movement of the platen which might cause "slur'ring is obviated. 1 By such an arrangement of the bed Band platenB greater strength with the least material is given, the

frame A A is relieved from bearing the strain of theiinpressions, and ,in manufacturing, the

bed and platen may be taken apart and put together with rapidity, so nccessaryin fitting the parts.

Directly beneath the bed- B is placed the ink-distributing cyliuder'l. This cylinder 1 may be supplied with ink from afountain in the usual way. Directly above the bed Bis placed the revolving ink-distributing tabular surface 2. Bythis arrangement of the "inking-surfaces I am enabled to give two distributions 6f ink to the inking-rollers for each impression,

'the rollers receiving a supplypf ink from the revolving ink distributing tabular surface placed upon one side of the form, as well as a supply of ink froma revolving cylindrical distributing-surface placed on the other side of the form. These means of distribution are admitted to be the bestin use, and by their combinationgin the manner shown I effect the most thorough means of distributingflthe ink yet presented.

3 are arms for the purposeot "carrying the inking-rollers 4 forward and backward over theform or types and the-ink-distributing surfa'cesjl and 2, as said arms 3 rock or vibrate.

These roller-arms 3 are connected together by a a brace, 5, and form, "as it were,'a frame.

and are connected to the studQ ,huiig' upon the frame AA, by means of the connection D.

The revolving ink-distributing tabular surface 2 is operated by a ratchet, E, whiledhe ink-distributing cylindrical surface 1 maybe made to vibrate and may be driven by a belt or gearing, as desired.

Oneithcr side of the platen l), and placed outside of thel'raine A A, are the gripper-supports I, hung upon the rod q. These supports Pt'arc hung back of the face-line of the platen 1%, and are slotted for the reception of the gripper Ff, held to the same as in Fig. l.

Upon the rod 9 is placed the spring T, which springr is operated by the counter-balance G in its movements.

frame is hung back of the face-line of the platen B, for the purpose of causing the grip per F, as it impinges upon the paper laid upon the platen, to push-the same (the paper) upward, thus straightening and smoothing out the sheet, while the forward end of thesheet is held in position by the sheet-taking nippers T T.

H" is a treadle'rod or'shaft running through the frame A A, to which treadle 'rod or shaft H the treadle 1, inside of the frame A A, is attached. This treadle rodor shaft H is fitted into journals on either side of the press. One end of the rod or shaft H is projected through the frame A A, which projected cud has'keyed upon it the crank-arm t, The crank-shaft a is properly fitted into the opposite end of this armt, so that .it may move freely. The opposite end of. the crank-shaft a is attached to or pivoted to the crank-shield c.

Inside of the frame A A, and upon the rod H, is swung the treadle .l, by which the press is operated. The purpose of thus constructing and operating the treadle 1 is, that by placing the single crank-shaft it outside of the press I can use a counter-balance of the full width that the insideof the press will allow; also, I can use a straight wrought-iron flywheel shaft, while at the same time the treadle shall be attached inside of the frame. j

The crank-shield c is keyed upon the extreme end of the fly-wheel shaftl, outside of the pinions H. This crank-shield 'u is used for a double purpose-namely, that of forming a shield to protect the operator or any one T in position to receive the sheet, the rollerarms 3 being at the lowestpoint of their vi- 'lhisspring 1' has one end of the elastic cord or spring attached to it, Q the other end of said cord or spring 8 being 4' eases roller 07. As the tripM continues its back ward movement or is withdrawn fromsupporting the c1'ank-arm c and roller (1, the spiral spring a closes the jaws. of the nippers T and T, which grip the sheet. The pin 0 uponthe.

' t 1 K mull-platen; B ;as shown;

causes the roller K to turn and wind up the,

trip ill nowstrikes against'the-cam shaped piece I), and, through the vibrating uprighta",

raises the gages z, allowing the sheet to be taken from the stationaryfeed-table'V by the nippers T T, The vibrating bedB, through the cranks, now commences its forward movement toward the platen B, for the purpose of giving the impression, and the Dipper-arms? P, operated by the cam N on the cog-wheel G,

4 commence to descend toward the face of the platen B, carrying with them the nippers T T, which nippers T draw the sheet under the gages z and from the stationary feed-table 'V. As the nipper-arms P P commence to descend toward the face of the platen B, the paper tympan-sheet J. is unwound from the roller K, and the sheet to be printed, being drawn oh" the stationary feed-table V, is received upon the paper tympan-sheet J. As the bed B continues to lmove-forward towardthe impression, the arms 1 I, carrying the nippers T and T, with the tympansheet J attached, continue their forward movement until the tympan' J and nippers T and Timpinge upon the lower edge of the platen B, and upon the still further movement of the arms P 1 the tympan-sheet J is drawn smoothly over the platen B, and the nippers T and T,

vibrating upon the shaft X, are lifted clear from the rod W, or its equivalent, and the forward ends of the ni ppers T and T then rest upon or are held up by the platen B. Thus the nipper-arms P P having reached their terminus of motion, the nippers, tympan-sheet, and sheet to be printed are brought into line with the face of the platen, ready for the reception of the impression. During this forward rocking movement of the nipper-arms P P- the bed B through the counter-balance G, has impinged against the spring upon the rod q, and-the gripper-frame attached to the rod is thrown toward the platen B slightly in advance of the bed B. \Vhen the nipperarms 1 I have reached their terminus of motion, above described, the gripper F, through the further movement of the bed B, impinges upon the sheet, gripping the sheet against the platen B. The bed B, still continuing to advance, impinges upon the platen B, and an impression is given. During the forward movement of the bed B the inking-rollers 4 have been carried from the ink-distributing cylindrical surface 1 up and over the form or types and onto'the revolving ink-distributing tabular surface 2. An impression having been given, the bed v.B-commences, through the cranks, its return movement from the platen B. As the bed B recedes,the sheetis relieved from the form or type by the gripper-F, and the counter-balance G gradually ceasing to spring 8 brings the gripper-frame back against the hubs 7, or into its first position. As soon as the sheet is properly relieved from the type,

the nipper-arms and nippers commence their return movement toward the stationary feedtable V. The elastic cord or spring attached tympan-sheet J. The movement of the nip- .per-armsl? P continuing, the crank-arm g, with its roller h, attached to-.the shaft X,

T, impinges upon the stationary slottedcain i, raising the nippers T and T, and admitting a volume of air between the nippers T pan-sheet J, attached to and operated by the nipper-arms B P and roller K, has now as sumed the inclined position necessary-tor the arm 6 upon the eccentric-shaft b impinges upon the trip M and rises upon the same, and through the eccentric (1 opens the nippers T and T, which releases the printed sheet from their grasp. During this upward movement v 'of the [ripper-arms and .tympan the forward 1 end of'the printed sheet has passed under shield or guide m, and such forward end of the sheet has been inclined or thrown down toward the pile-table V", and upon being reneath the sheet catches or holders k k, as fully described. Whenthe bed B has completed its return movement, the rollers 4, carried from the revolving ink-distributing tabular surface 2, having received a supply of ink the time of the delivery of the .printed sheet have reached the ink-distributing cylindrical surface 1, or their point of starting. The sucupon the stationary feed-table, the operation toward'the operator, and the sleeve D is rocked until its plane part is brought to bear against the platen-support 21, the platen B vibrating from the point of receiving the impression. The nippers T and T, resting upon the platen press upon thespring r, the elastic cord or upon which shaft X are the nippers T and 1 and T and the tympan-sheet .J. The tymdelivery of the printed sheet, and the crank leased from the nippers the printed sheet is properly deposited upon the 'pile-tableVflbel therefrom, have passed overthe form, and at ceeding sheet have been laid against the gages just described is repeated. When required to suspend theimpression, the handle 0 is drawn B, as described, are made to vibrate with the roller, 0, attached to the arm 0, the operation of the nippe'itarms P P, nippers' T and T, and rolling tympan-sheet J is suspended; The sheet is then laid directly upon the platen '13, instead of being laid upon thefeed-table V, as previously described.

Having thus described my invention,what I claim therein as new, and desire to secure by Letters Patent, ist 1. A platen which shall be stationary for the reception of the sheet and for the reception of the impression, (a) when such platen shall be vibrated for the purpose set forth,(b)
